Some clever genetic manipulation has led scientists to identify the chemical that allows daylength to trigger flowering in plants – all plants, it looks like. It is the protein produced by the gene called Flowering Locus T, or FT. This means that crop beeders will now have a better shot at developing varieties which will flower at different latitudes, useful as climate zones shift due to climate change.
China data
USDA has made available a whole bunch of time-series agricultural data for China, at both national and provincial levels. Truly amazing stuff, some of it going back to 1949. Here’s the trend in peanut production in Anhui province for the past 25 years.
Using native plants
It may be a bit of a stretch for this blog, but I liked a recent Christian Science Monitor article on the increasing use of native plants – at the expense of exotics – for landscaping in some parts of the US. The authors credit more awareness of climate change, and in particular worries about excessive water use in ever more drought-prone areas, for this shift in attitudes.
Welsh pony in trouble?
A long article in icWales, the self-described “national website of Wales,” details the predicament of the local pony breed. Once an important part of everyday rural life – and indeed industrial life, due to their use in coal mines – more recently a children’s trekking pony, there is now limited demand for the breed. Wild herds have thus declined dramatically, no doubt resulting in genetic erosion. Does it matter? A resounding yes echoes around the hills.
Chinese fungi and tea
I’m killing a few hours at Hong Kong International Airport, so I pick up the latest issue of China Today. There’s a number of really interesting articles, but two little snippets jumped out at me. The first is a short note on the Chinese Caterpillar Fungus, Cordyceps sinensis. No, I’d never heard of it either, but it turns out that it is important in Chinese traditional medicine, and that it has not been possible to grow it in the lab. Until just now that is, hence the note in the Sci-tech Info section announcing the possibility of mass-production.
The other really nifty piece of sino-information occurs in the opening section of an Around China piece on the Zhenyuan Yi-Hani-Lanu Autonomous County. It seems that this ancient tea-growing area, with its tea-dominated forests, boasts what is considered the oldest and largest tea plant in the world. At 25 metres tall, almost 3 metres in diameter and an alleged 2,700 years of age, it is apparently quite the tourist attraction, and “its fleshy, glossy leaves produce a strong and lasting flavour.”
